A noose made out of juice boxes that have been emptied, flattened and rolled taut. Krazy Glue (TM) is generally used to hold the boxes together -- trial and error practices over time have indicated that this is the only material strong enough to hold the nuise together even against the pressure of sometimes exorbitant body weights. In certain cultures orange juice (from concentrate) boxes are used, but, and this is subject to the varying degrees of deference a culture has for their particular nuise practices, many use apple juice boxes (Mott's is a particular favorite).
"Dude, did you see that nuise? It was tight, yo."
"Only someone ridiculously stupid would misspell noose as nuise."
